Same Blood Group Doesn’t Affect Pregnancy – RH Factor Is The Real Concern, Say Experts

Lucknow, July 18, ( TNA) Contrary to popular belief, having the same blood group (A, B, AB, or O) between partners does not affect fertility or the ability to conceive a child. According to medical experts, the real issue lies in RH factor incompatibility, not the main blood type.

What is RH Incompatibility?

RH incompatibility occurs when the mother is RH-negative and the father is RH-positive. If the baby inherits the RH-positive factor from the father, the mother's immune system may see the baby’s blood as a foreign substance and start producing antibodies. This immune reaction is usually not harmful during the first pregnancy, but it can seriously affect future pregnancies.

Potential Risks for the Baby:

• Hemolytic disease of the newborn

• Anaemia

• Jaundice

• Brain damage (in severe cases)

How to Prevent RH Incompatibility Complications

Today, RH-negative pregnant women can receive an Anti-D immunoglobulin injection, which prevents the formation of antibodies and protects future pregnancies.

Why Pre-Marital Blood Tests Matter

Doctors strongly advise pre-marital blood testing to:

• Detect RH factor incompatibility

• Screen for genetic disorders like thalassemia and sickle cell anaemia

• Identify STIs such as HIV, Hepatitis B/C, and syphilis

• Assess overall health indicators like haemoglobin levels, blood sugar, and liver/kidney function

• Understanding blood group compatibility and taking preventive steps before marriage can help couples plan a healthy family and prevent avoidable complications. Don’t let myths misguide you—consult your doctor and get the right blood tests done
